MicroRNAs (miRNAs) negatively and post-transcriptionally regulate expression of multiple target genes to support anabolic pathways for bone formation. Here, we show that miR-218 is induced during osteoblast differentiation and has potent osteogenic properties. miR-218 promotes commitment and differentiation of bone marrow stromal cells by activating a(More)
NG2 is a high-molecular-weight chondroitin sulphate proteoglycan found on the surfaces of oligodendrocyte precursor cells (OPCs). Here we review the history and biology of OPCs with an emphasis on their functions after experimentally induced CNS injury. Injury to brain or spinal cord results in the rapid accumulation of NG2-expressing OPCs in the glial scar(More)
OBJECTIVE To evaluate the frequency of sensitization to Aspergillus antigens and the prevalence of allergic bronchopulmonary aspergillosis (ABPA) in asthmatic patients. METHODS Two hundred consecutive non-smoking outpatients with asthma (≥ 18 years) underwent skin testing with aeroallergens, peripheral eosinophil counting, measurements of total serum IgE(More)
Nonsyndromic cleft lip with or without a cleft palate (NSCL/P) is among the most common human congenital birth defects and imposes a substantial physical and financial burden on affected individuals. Here, we conduct a case-control-based GWAS followed by two rounds of replication; we include six independent cohorts from China to elucidate the genetic(More)
In this paper, the method for the derivatization of carbohydrates with 1-phenyl-3-methyl-5-pyrazolone (PMP) was simplified. One-third of the derivatization time was saved. Five monosaccharide derivatives have been well separated by MEKC and HPLC under optimized conditions. Good reproducibility could be obtained with relative standard deviation (RSD) values(More)
The aim of this study was to compare and evaluate the anchorage effectiveness of using either micro-implants or extraoral headgear with the McLaughlin-Bennett-Trevisi (MBT) system. Thirty young Chinese adults (14 males and 16 females) aged 18-22 years with anterior bimaxillary protrusion were divided randomly into two equal groups, treated with the MBT(More)
Melatonin is a highly conserved molecule that not only exists in animals, but also is present in bacteria, unicellular organisms and in plants. Since melatonin is an antioxidant, in plants melatonin was speculated to protect them from intrinsic and environmental oxidative stress. More importantly, melatonin in edible plants inevitably enters animals and(More)
Human adipose-derived stem cells (hASCs) have become a highly attractive source of seed cells in bone regenerative. It has become a key issue how to effectively improve osteogenic differentiation of hASCs in the bone tissue engineering. Numerous regulatory pathways dominate osteogenic differentiation of hASCs involve transcriptional factors and signaling(More)
Tooth agenesis is one of the most common developmental disorders in humans. The PAX9 gene, which plays an important role in odontogenesis, is associated with familial and sporadic tooth agenesis. A case-control study was performed in 102 subjects with tooth agenesis (cases) and 116 healthy controls. We genotyped four PAX9 gene polymorphisms using a(More)
This study was specifically designed to identify anticancer constituents in methanol-water extract of Polygonum bistorta L. and evaluate its cytotoxicity. For this purpose methanol-water (40:60 v/v) extract was subjected to conventional preparative high pressure liquid chromatography and 13 fractions were obtained. Constituents of obtained fractions were(More)
